amplitude of a photon

What amplitude does an electromagnetic wave have? We know the wavelength
relates to how much energy the photon has, but what does the amplitude of
the photon indicate? Is the amplitude the same for all electromegnetic
waves?

A photon doesn’t have an “amplitude”, it has an energy determined by
the frequency/wavelength.

The amplitude of an elecromagnetic wave is determined by the number of
photons in it.

The square of the amplitude is proportional the average energy density of
photons in a certain volume,
or respectively proportional to the average number of photons flowing
through a surface per time unit.
